Abstract
The invention discloses a paint spraying method for injection molded products. The paint spraying method includes: deoiling an injection molded product, drying the injection molded product for 20-30 minutes, polishing the injection molded products for 0.1-0.3 millimeters, spraying 0.2-0.3mm thickness of primer paint on the injection molded product, drying the injection molded product for 2-3 hours after primer paint spraying, and spraying 2 layers of gloss oil on the injection molded product after the surface of the injection molded product is dried. The paint spraying method for the injection molded products has the advantages that adhesive force of a coated layer is increased effectively, quality of the injection molded product is improved further, and operation steps of the paint spraying method are simple and easy to control.
Description
Technical field
The present invention relates to a kind of plasthetics processing method, particularly relate to a kind of injection-molded item method for paint spraying.
Background technology
The spraying of injection-molded item is an important step, the quality of coating quality directly affects the quality of injection-molded item, but the step of hell to pay also can cause the waste of time and personnel, and spraying method of the prior art is too complicated, is unfavorable for large batch of operation.
Summary of the invention
The technical problem that the present invention mainly solves is: the adhesive force that effectively can promote coating surface, further promotes the quality of injection-molded item, and operating procedure is simple, easy to control.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of injection-molded item method for paint spraying, comprise following operating procedure: first carry out deoiling at injection-molded item, dry, polish, the time of drying is 20-30min, and polishing thickness is 0.1-0.3mm, then primer spray on injection-molded item, the thickness of priming paint is 0.2-0.3mm, carry out drying after having sprayed priming paint, drying time is 2-3h, sprays 2 layers of gloss oil after dry tack free again.
In a preferred embodiment of the present invention, described gloss oil is UV gloss oil or PU gloss oil.
In a preferred embodiment of the present invention, the thickness of described every layer of gloss oil is 0.1-0.3mm.
In a preferred embodiment of the present invention, described in deoil in step and include polyoxyethylene alkylphenol ether.
The invention has the beneficial effects as follows: the adhesive force that effectively can promote coating surface, further promote the quality of injection-molded item, and operating procedure is simple, easy to control.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides following technical scheme.
A kind of injection-molded item method for paint spraying is provided in the present embodiment, comprise following operating procedure: first carry out deoiling at injection-molded item, dry, polish, the time of drying is 20-30min, polishing thickness is 0.1-0.3mm, then primer spray on injection-molded item, the thickness of priming paint is 0.2-0.3mm, carries out drying after having sprayed priming paint, drying time is 2-3h, sprays 2 layers of gloss oil after dry tack free again.
Described gloss oil is UV gloss oil or PU gloss oil, and the thickness of described every layer of gloss oil is 0.1-0.3mm, is preferably 0.2mm.
Preferably, polyoxyethylene alkylphenol ether is included in step of deoiling described in.
The invention has the beneficial effects as follows: the adhesive force that effectively can promote coating surface, further promote the quality of injection-molded item, and operating procedure is simple, easy to control.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
